[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a wireless headset according to an embodiment of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is a diagram showing an appearance of a headset according to an embodiment of the present invention.
[0011]
As shown in the figure, a headset 1 according to one embodiment of the present invention includes a pad 16 attached to a housing and a microphone 11 that collects voice from a user.
[0012]
FIG. 2 is a diagram showing a case where the headset 1 shown in FIG. 1 is mounted.
[0013]
In the figure, the user can listen to music or the like via the pad 16 having a built-in speaker that outputs wireless data transmitted from the player main body 41, received by the headset, and outputs decoded audio data. After acquiring the user's voice by 11 and encoding the voice signal of the obtained voice, the voice signal can be transmitted to the player main body 41 wirelessly by an antenna (not shown).
[0014]
The pad 16 of the headset 1 can be tilted as shown in FIG. 3 by a pad tilting mechanism (not shown). By inclining the pad 16 in this manner, when the user speaks to another person, the user can often hear the other person's talk without removing the headset. Further, in the headset of the present embodiment, the sound signal transmitted from the player main body is controlled by the manner of tilting the pad.
[0015]
In addition, in the example shown in FIG. 3, the case where the pad 16 is inclined in the horizontal direction is shown, but the present invention is not limited to this. For example, the pad 16 may be inclined forward or backward.
[0016]
FIG. 4 is a block diagram showing functions of headset 1 according to the embodiment of the present invention. The same parts as those in FIG. 1 are denoted by the same reference numerals.
[0017]
In FIG. 1, a microphone 11 acquires audio from a user, and an audio amplifier 12 amplifies an analog audio signal acquired by the microphone 11. The modulator 13 modulates the analog audio signal amplified by the audio amplifier 12 into a digital audio signal.
[0018]
The transmission filter 14 filters the digital audio signal modulated by the modulator 13 and outputs a digital audio signal in an audio band.
[0019]
The antenna 15 wirelessly transmits the filtered digital audio signal from the transmission filter 14 to the player main body 4 and receives the digital audio signal transmitted from the player main body 4.
[0020]
The reception filter 21 filters the digital audio signal received via the antenna 15 and outputs a digital audio signal in an audio band.
[0021]
The demodulation unit 20 converts the digital audio signal filtered by the reception filter 21 into an analog signal.
[0022]
The switching unit 19 switches audio mute based on an instruction from the control unit 23.
[0023]
The audio amplifier 18 amplifies the analog audio signal demodulated by the demodulator 20 and input via the switch 19.
[0024]
The speaker 17 is housed in the pad 16 and outputs an audio signal amplified by the audio amplifier 18.
[0025]
The pad 16 has a speaker 17, and is attached to the housing so as to be tiltable in a predetermined direction by a pad tilting mechanism 27.
[0026]
The pad tilt detection unit 22 detects the tilt of the pad 16 tilted by the pad tilt mechanism 27.
[0027]
The control unit 23 controls the entire headset, and includes a tilt determination unit 31, a volume determination unit 32, an elapsed time detection unit 33, a mute unit 34, a mute release unit 35, and a power cutoff unit 36. .
[0028]
The inclination determination unit 31 determines whether the inclination of the pad detected by the pad inclination detection unit 22 is equal to or greater than a predetermined inclination.
[0029]
The volume determination unit 32 detects that the audio signal input from the microphone 11 and amplified by the audio amplification unit 12 is equal to or higher than a predetermined volume.
[0030]
When the inclination determining unit 31 detects that the inclination of the pad is equal to or greater than the predetermined inclination, the elapsed time detection unit 33 refers to the value of the timer 24 and enters a state where the inclination of the pad is equal to or greater than the predetermined inclination. It detects that a predetermined period of time has elapsed since then.
[0031]
The muting unit 34 mutes the sound output from the speaker 17 by outputting a control signal to the switching unit 19 when the inclination determination unit 31 determines that the inclination of the pad is equal to or greater than the predetermined inclination.
[0032]
The mute canceling unit 35 outputs a control signal to the switching unit 19 when the inclination determining unit 31 determines that the inclination of the pad is smaller than the predetermined inclination in a state where the sound is muted. The mute of the sound output from 17 is released. Further, in a state where the sound is muted, the sound volume determination unit 32 switches the switching unit when the sound signal input from the microphone 11 and amplified by the sound amplification unit 12 is higher than a predetermined sound volume. By outputting a control signal to 19, the mute of the sound output from the speaker 17 is released.
[0033]
The power cutoff unit 36 outputs a control signal when the elapsed time detection unit 33 detects that the pad inclination is equal to or greater than the predetermined inclination by the inclination determination unit 31 and then detects that a predetermined time has elapsed. By sending the signal to the switch 26, the power supplied from the power supply 25 to each component of the wireless headset is cut off.
[0034]
Next, the operation of the wireless headset according to the embodiment of the present invention will be described with reference to the flowchart in FIG.
[0035]
First, it is determined whether the pad is tilted (S1). If it is determined in S1 that the pad is tilted, then it is determined whether the tilt of the pad is equal to or greater than a predetermined value (S2). This determination is made by the inclination determination unit 31.
[0036]
If it is determined in S2 that the value is not equal to or larger than the predetermined value, the process returns to S1. On the other hand, when it is determined that the value is equal to or more than the predetermined value, the mute unit 34 mutes the sound (S3). Thus, in the case where another person speaks, the sound is muted by tilting the pad, so that the other person's speech becomes easy to hear. Although the case where the audio is muted has been described here, the power of the audio may be reduced.
[0037]
Next, in a state where the sound is muted, it is determined whether or not a sound input of a certain volume or more has been made to the microphone (S4). This determination is made by the volume determination unit 32.
[0038]
If it is determined in S4 that a voice input of a certain volume or higher has been made, the mute of the voice is canceled (S5). The muting of the audio is released by the mute releasing unit 35. When the audio power is reduced, the audio power is restored.
[0039]
On the other hand, if it is determined in S4 that there is no voice input with a certain volume or higher, then it is determined whether or not the inclination of the pad is less than a predetermined value (S6). This determination is made by the inclination determination unit 31.
[0040]
If it is determined in S6 that the inclination of the pad is smaller than the predetermined value, the mute of the sound is canceled (S5). When the audio power is reduced, the audio power is restored. If it is determined in S6 that the inclination of the pad is not less than the predetermined value, then it is determined that the inclination of the pad is equal to or more than the predetermined value. It is determined whether or not a predetermined time has elapsed since the last time (S7). This determination is made by the elapsed time detection unit 33.
[0041]
If it is determined in S7 that the predetermined time has not elapsed, the process proceeds to S3. On the other hand, if it is determined in S7 that the predetermined time has elapsed, the power of the headset is shut off (S8). The power of the headset is cut off by a power cutoff unit 36.
[0042]
Therefore, according to the wireless headset according to the embodiment of the present invention, the sound can be muted by tilting the pad of the wireless headset, so that the trouble of removing the wireless headset can be saved, and the wireless headset can be connected with another person. Makes conversation easier.
[0043]
In addition, after a predetermined period of time has elapsed after muting the sound by tilting the pad, the power of the headset can be cut off, so that the power consumption of the wireless headset can be reduced.
[0044]
Note that the present invention is not limited to the above embodiments, and various modifications can be made in the implementation stage without departing from the scope of the invention.
